It simply like other young detective series. At first Haruya is not a detective, he was asked to help Miu to solve stalking issue, then he agreed because of the reward money. Since then, he does several cases that happened around him. He always does it because of the reward, especially money. Haruya is quite popular in his university because he's good looking. His personally is easy going and a bit mysterious for me, he is a son from rich family but his parent never gives him allowance money so that's why Haruya always doing investigation and detective-like with his friends (Kazuomi, Toshiki & Miu) for money. IMO, the cases in this series are much simpler than the usual young detective series that I always watch (let's say it's Kindaichi series). Each episode contain 1 case so it's easy to be followed without leaving curiosity and suspense at the ending. Some of them are about stalking, kidnapping, fraud, peeping tom, bullying and blackmailing. The first half from the entire episode almost just 'oh' or not that much thrilling but the second half of the series getting better with some more serious cases. And the romance that a little bit developed, it makes this series more interesting in the end. The way he solve those cases also much simpler, there is no such mathematical technique but it does involve some action scene. Even though the action scenes sometimes a bit weird, for example the bad guy was defeated with just one punch in the face and Tamamori Yuta's serious face was cute for some reason (LOL). In the ending I'm a bit disappointed because it's look like there are a lot of interesting things that need to be dug up so I hope there will be season 2. It's fun seeing the interaction between the casts and I hope they will expose more about Haruya's family, his past (in the episode 5 there is someone said that actually Haruya is a famous and dangerous thug) and also his romance life a bit, its so cute seeing Haruya keep being pushed by Miu.
